Melotte 15 - 26.8.2020 at 00.00 - 26.8.2020 at 02.00 Pori Observation number 93176

Visibility III / V

Jarkko Suominen, Porin Karhunvartijat

Last season went a bit with the hardware in bad luck. Now I finally got the hardware to work ... so like. Namely, just before the discovery, my old reliable guide camera said that now is enough.

Together with Tomi Kurri, we went to describe and visually observe the objects of the deep sky. My own goal was to get Melotte 15 and the surrounding heart mist for the cell.

I managed to get only 30min until the battery started to clot (today luckily a new battery for my laptop came in the mail) ...

But does something still work with that old ATIK 16IC camera? Or what do you think?

The description at the time of the weather was quite foggy, but still brightened when my battery ran out XD. We then visually looked at the sky from a few objects on Tom’s tube.

      In an emission nebula the hot stars nearby cause the gas glow. This should not mix with reflection nebula, where the gas is only lit up by nearby stars.

      The appearance of a gas nebula is irregular, and the fainter parts of it need bigger instruments to be visible.


      Emssion nebulae in Cepheus. The bigger part is composed of the nebulae Cederblad 214 (Ced214) and NGC 7822. The lower round nebula is called Sharpless 170 (Sh2-170). Image J-P Metsävainio.

      In this 4-degree-field there are emission nebulae Sh2-157, Sh2-158, Sh2-159, Sh2-161 and Sh2-162 (or NGC 7635 aka Bubble Nebula) and open clusters M52 and NGC 7510. Image Juha Kepsu.


      NGC 281 aka Pacman Nebula. The object is in Cassiopeia. Image J-P Metsävainio.


      NGC 896 in Cassiopeia is the tip of Heart Nebula (IC 1805). Image Timo Inkinen.

  • Star clusters and asterisms
    • Open cluster info

      Open cluster is an irregular group of tens or hundreds of stars. It can be visible as separate stars or a bit fuzzy spot with small instrument.

      There is the open cluster M52 on the right edge of the image. The red emission nebula is the Bubble Nebula. Image Jyrki Grönroos.


      The open cluster M45 aka Pleyades. Image Juha Parvio.

      M34 is also an open cluster in Perseus. Image Teppo Laitinen.


      The Wild Duck Cluster M11 is an exceptional dense open cluster. Image Jaakko Asikainen.
